mpg
We have to remember that a diesel eats fuel everytime you hear that turbo whistle. If you can keep your foot out of it and drive it like a truck and not a race car the MPG will go up!! If you are speeding with a 8000# truck the MPG #'s drop very fast over 65.
I would loke to add also that all the MPG #'s that the Cummins guys claim are with 3.54 gears. When they went to 3.73's in 2003 thier #'s dropped. I would like to also mention that their trucks are atleast 500-1000#'s lighter than ours.
This is my 2 cents

2003 Dodge 5.9, DRP 85hp Module, 48re trans, stock wheels tires, 3.73 rear gear, Green air filter, Gen49D fuel additive, 4x4, four door. 65 psi in all four tires stock BFG tires. I drive 81mph on the interstate and 72mph on the two lanes. Best fuel mileage at 81mph was 19.38mpg filled up, set the cruise at 81mph and didn't touch it for 400 miles. Best on the 72mph two lanes was 21.5. It has done that a few times. The truck will get 18-19 mpg every time on the 81mph trips and 19-21 on the 72mph trips. The low 20's are the norm on the 72 and mid 18's on the 81mph.
Towing at 81mph 26 foot car hauler with tools, living quarters and tons of misc stuff the truck gets 10.5-12mpg depending on the wind. It did get 9.5 once but the wind was horrid. Towing at 72mph the truck gets 11-13 depending on the wind. I've pulled heavier loads and got better fuel mileage but, the car hauler is over tall with two air conditioners and stuff. It seems to hurt the mileage more than weight.
Before you ask why a guy driving a Dodge is on a Ford site its simple. I bought my '03 in late '04 because the new Dodges weren't getting great mileage, the Ford was having tons of engine issues and I didn't like the Duramax that much. I bought the Dodge for it's dependability and I knew they got decent fuel mileage (not as good as my 2001 Dodge). I like the looks of the Ford and their body/frame construction. I am waiting for them to get their engine program together and I might purchase one next. I absolutely love the interior on the new 6.4 and the exterior look is still the best even with the funny front end. I keep VERY up to date on all the makers' diesel programs. I don't dislike any of them. I really am a non brand loyal, non biased buyer. I do heavy research before I spend my money.
My truck did pretty well on fuel before the module was installed. At 81mph it would get 17.8-18.8 at 72mph it would hit high 19's generally getting low to mid 19's. The module helped the towing mileage quite a bit. It bumped it 1-2mpg depending on the wind. I once got 8.9mpg, driving 78mph with the car hauler across I-80 in a HUGE head wind, when the truck was all stock. The wind was the worst I had ever pulled in. When it was a little bit of a cross wind I would slow down for safety concerns even though the trailer and truck felt fine. It was that bad!
I am hoping to see the mileage improve on the 6.4 when they get a few miles on them. I don't buy diesel trucks new because I'm cheap and don't like waiting 25,000 miles for better power and fuel economy. I generally buy them with 20-30,000 miles on them and run them till I'm tired of them. I can also check their history for engine issues. They ALL have engine issues from time to time. Even the glorious Cummins.
Now I know of several people with all the makes that get good fuel mileage with similar driving habits. I do know several that get a lot worse. I know of one reason that happens. The injector build quality, from the big three, stinks. If you get a truck with the lower percentage of quality injectors the truck suffers in economy and power. Just the opposite for the higher percentage. That is the main reason Joe Bob gets 12 mpg and Jim Bob gets 15mpg with similar driving habits. I test drive vehicles and rest the fuel display. I drive them on the same route, whenever possible, and pick the one that displays the best mileage. It hasn't failed yet. My friends have done this with new trucks and it proves true. My brother picked one (a Dodge) that displayed 13mpg on the test drive because he liked that "one" best. It has been a fuel pig since new.
Now please give me you opinion.

"The old school GM 6.2L diesels got 20+ MPG all the time. They weren't fast, but they would get great mileage."
I am sure that no one on this site cares what mileage a chevrolet diesel/gas hybrid got for economy. Back when that was made it would have been better to buy a 454 for the power than a 6.2 with no power. I am however happy to hear that you used to have a 6.2. I would be interested to see what you have now?

Just refueled. That's the second tank used. I drove 480 miles with about 375 being highway at 65mph and balance at 35-45 mph. I averaged 14.5 mpg. Pretty well the same as my first tank. There is now 1,000 miles on my truck so maybe she will get better now. Mine is a 2008 350 4X4 6.4PSD long box with 373 ltd slip. This is the first diesel I ever owned and right now she is getting 20% better fuel economy than my 2005 5.4l (351) gas F150.

Strange how all the new guys seem to need a math lesson
distance traveled in miles / gallons used = MPG (Must be filled to the same level each time)
There is no way you are getting near 20mpg at 80 mph.......... Period ........
Joe whitetail needs to find a different site also!!!!!!!!!!!!!!!
FYI: Motor Week has a 24v Dodge that they are using for a long term tester and they are reporting an average mileage of just under 15 MPG that is a combined use total and no towing is included.
So if you have one that is averaging 19+ you ought to keep it.

I once got 8.9mpg, driving 78mph with the car hauler across I-80 in a HUGE head wind, when the truck was all stock. The wind was the worst I had ever pulled in. When it was a little bit of a cross wind I would slow down for safety concerns even though the trailer and truck felt fine. It was that bad!
I am hoping to see the mileage improve on the 6.4 when they get a few miles on them. I don't buy diesel trucks new because I'm cheap and don't like waiting 25,000 miles for better power and fuel economy. I generally buy them with 20-30,000 miles on them and run them till I'm tired of them. I can also check their history for engine issues. They ALL have engine issues from time to time. Even the glorious Cummins.
Now I know of several people with all the makes that get good fuel mileage with similar driving habits. I do know several that get a lot worse. I know of one reason that happens. The injector build quality, from the big three, stinks. If you get a truck with the lower percentage of quality injectors the truck suffers in economy and power. Just the opposite for the higher percentage. That is the main reason Joe Bob gets 12 mpg and Jim Bob gets 15mpg with similar driving habits. I test drive vehicles and rest the fuel display. I drive them on the same route, whenever possible, and pick the one that displays the best mileage. It hasn't failed yet. My friends have done this with new trucks and it proves true. My brother picked one (a Dodge) that displayed 13mpg on the test drive because he liked that "one" best. It has been a fuel pig since new.
Now please give me you opinion.

Towing at 81mph 26 foot car hauler with tools, living quarters and tons of misc stuff the truck gets 10.5-12mpg depending on the wind. It did get 9.5 once but the wind was horrid. Towing at 72mph the truck gets 11-13 depending on the wind. I've pulled heavier loads and got better fuel mileage but, the car hauler is over tall with two air conditioners and stuff. It seems to hurt the mileage more than weight.
Before you ask why a guy driving a Dodge is on a Ford site its simple. I bought my '03 in late '04 because the new Dodges weren't getting great mileage, the Ford was having tons of engine issues and I didn't like the Duramax that much. I bought the Dodge for it's dependability and I knew they got decent fuel mileage (not as good as my 2001 Dodge). I like the looks of the Ford and their body/frame construction. I am waiting for them to get their engine program together and I might purchase one next. I absolutely love the interior on the new 6.4 and the exterior look is still the best even with the funny front end. I keep VERY up to date on all the makers' diesel programs. I don't dislike any of them. I really am a non brand loyal, non biased buyer. I do heavy research before I spend my money.

I was a Chevy truck person for 20 years, after owning my 1st Ford in 99, I came to believe Ford makes a better truck. I bought a Ford to tow heavy, not for Fuel milage. Yes I would like both, but the real world is not like that. It is either one or the other. Ford works best for most of us. Still GM man when it comes to cars. My Firehawk gets 20mpg at 100 mph but so what!

Jwhitetail. I mean no negative comment here but I am involved in this thread just to see what mpg my Ford 2008 6.4 350 psd should get and what others with similar vehicles are getting. I do not see the users of this thread claiming Ford is better than the GM for mpg or otherwise. Probably the reason most of us bought Ford has nothing to do with mpg. Still though we like to discuss with other owners of the same vehicle how we are doing in mpg.
